Generating a functional coverage model from a trace

Abstract

A functional coverage model may be generated based on a trace. The functional coverage model may comprise values of attributes. The values may be extracted from one or more entries comprised by the trace. Based upon a selection of a field of an exemplary entry, content of the corresponding fields in other entries may be extracted and utilized. In some exemplary embodiments, names of attributes may be extracted from the trace. In some exemplary embodiments, a reference trace may be utilized as a comparative baseline coverage by generating a functional coverage model based upon the reference trace and comparing coverage of a second trace in respect to the functional coverage model with the coverage of the reference trace.
